downloading ringers from website

HiI'm a new owner of an Alltel LG8600 and need help figuring out how to download ringers from a website. I spent an hour at my local Alltel store and he couldnt even tell me how to bookmark a page. I've googled some info and it talks about a USB cable, Jumpmusic and Bitpim. I'm not tech-savvy but any info would be greatly appreicated! Thanks
